FLOOR CONNECTION.

Specification of Letters Patent.

Patented Mar. 17, 1914.

Application filed July 19, 1911. Serial No. 639,681.

To all whom it may concern Be it known that I, THOMAS E. GRosBY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Floor Connections, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to means for con necting certain plumbing fixtures, such as sinks, water closets and analogous fixtures, especially of the porcelain or earthenware type, with closet bends and form a perfect gas and water tight connection between the same when the fixture has been properly secured upon the floor and connected to said closet bend.

The principal object is the provision of a reversible, interchangeable floor plate for earthenware traps.

Another object of this invention is to provide a simple and eiiicient connection of this character which may be easily, quickly, and accurately mounted in place in connection with fixtures having the spigot or nipple as well as on those that are recessed and without the amount of expensive labor necessary to install floor connections of that type now commonly used.

Further objects are the ready adjusting of parts to obtain a perfect joint between the closet bend fixture so that escape of sewer gas or air may be prevented, and to secure facility of detachment, adjustment and replacement as may be required and without liability of breakage of any of the parts.

My improvements involve certain novel and useful combinations or arrangements of parts, peculiarities of construction, and principles of operation, as will be hereinafter fully described, in order to accomplish the above mentioned objects, and to'seoure other and further advantages in the matter of construction, operation, and use.

Of the drawings: Figure 1 represents a vertical central section showing my improved floor connection and reversible floor plate applied to an earthenwaretrap ofthe recessedtype. Fig. 2 represents ahorizontal transverse section of the same, the cutting plane being on line 2-2 on Fig. 1. Fig. 3 represents a slde elevation of the reversible floor plate showing in dotted lines the tooth on the sleeve in the same position as shown in Fig. 1, about half way up on the segmental rack of the reversible floor plate. Fig. 4 represents a fragmentary inner side view of a portion of the same, showing in dotted lines one of the teeth on the sleeve passing between two of the segmental racks. Fig. 5 represents a vertical central section showing my improved floor connection and the same reversible floor plate, asshown in Fig. l, as applied to an earthenware trap of the spigot or nipple type. Fig. 6 represents an elevation of the-bottom of the sleeve, and Fig. 7 represents a central sectional elevation of the top portion of the sleeve as it appears before adjustment to the closet.

Similar characters designate like parts throughout the several figures of the drawings.

The numeral 8 indicates the lower or under floor of a room properly recessed as at 9 to receive the flanged end 10 of the hub 11 of the closet bend. The top or upper floor 12 of tile, wood, or other material, is provided with a smaller opening to allow the sleeve, or what is commonly termed in plumbing the ferrule, 13 to extend therethrough. It is customary to abut the hub 11 against the under side of the upper floor, as is shown in Fig. 1 and to fill the space intervening between the outside of the sleeve and the inner side of the hub with oakum and lead. It is also common to rest the bottom portion 14 ofthe hopper 15 upon the floor and bolt the same to the floor plate.

My invention therefore consists in the new and improved form of floor plate, the new and improved form of closet bend, and the new and improved means of connecting the parts together.

The upper portion of my sleeve is dome shaped as at 16, being provided on the periphery near the upper edge of the dome with one or more lugs 17, preferably three in number, and formed integral with the sleeve. The lugs are broad at their upper part, as shown in dotted lines in Figs. 3 and 4 and'extend downwardly forming a V shaped tooth which tooth is curved from the top edge of the sleeve to the outer end, of the tooth edge. When the sleeve is properly secured in place the upper edge of the sleeve will abut against the inner under side of the bottom portion 14 of the hopper, as shown in Figs. 1 and 5, although it is apparent without further illustration that if desirable a packing ring or washer could be inserted between these two parts to further prevent any leakage.

My reversible floor plate consists of a flat surface 18 provided with one or more seg mental slots 19, preferably three in number, a peripheral flange extending around the portion 18 and below the surface as at 21 and above the surface as at 22, which flange 20 rests upon the floor surface in every case after the parts are properly adjusted. The inner edge of the surface 18 is provided with a series of flanges 23 at right angles to the surface, the lower portion of the flanges 23 being horizontal and the top portion being inclined and carrying at right angles to it a segmental toothed rack or runway provided on its upper side with the teeth 25 and on its under side with the teeth 26. These racks 24; are inclined upwardly clockwise so that when the racks have been inserted between the teeth 17 and the floor and the closet bend has been adjusted to the proper height the floor plate may be turned about its axis until it is firmly wedged between the lug 17 and the floor 12, all retrograde movement of said plate being pre vented by the coaction of the teeth 17 with the teeth 25 or 26 on said racks 24. In Fig. 1, I have shown the plumbing fixture 15 and floor plate 18 secured together by a T bolt 27, the head of which is turned sufliciently to wedge against the inner sides of the flanges 20 and 23 to prevent further turning so that the nut 28 may be turned thereon until the parts are all securely locked.

When a spigot or nipple trap is used the nipple ordinarily extends downward into the upper portion of the sleeve as at 29 and as there is less space between the floor level and the inner under slde of the hopper adjacent to the nipple 29 I reverse the floor plate 18 so that instead of the teeth 17 running along the teeth 25 onthe upper side of the racks 2 1 they run along the teeth 26 on the underside of the racks as the sleeve is turned contra clockwise, and the T bolts are adjusted. In water closets of the porcelain type there are ordinarily used two of these bolts, one on each side of the closet and therefore in Fig. 2, I have shown only two of these bolts, the third segmental slot not being in use.

The sleeve 16 is provided with a series of indentations 30 which extend around the lower portion thereof and are adapted to receive a portion of the packing material inserted between said sleeve and the hub 11.

. The lower peripheral rib 31 on the sleeve is ble by having a top plate or cover 32 which may rest in a recess 33 extending around the inner edge of the top rim of the sleeve, with the edge of the rim pressed over to secure the plate and prevent leakage. If desired the plate may be cast integral with the sleeve. V

The hub 11 of the closet bend is brought up through the recess 9 in the under floor until it abuts the under side of the top or upper floor 12; while the ferrule or sleeve 13 is seated on the inner side of the hub, the space intervening between the inner side of the hub and the outside of the sleeve being filled with oakum and lead 34. The floor plate is put in place around the sleeve, resting on the floor, it being turned so that the upper surface of the segmental toothed racks or runways 24 pass beneath the teeth 1 r 17. The sleeve is adjusted so that its top rim is substantially the same height from the floor as the distance in the deeper recess in the under side of the hopper 15, which latter is then placed over the floor plate and sleeve with the bolts 27, previously inserted in place so as to extend upwardly from the floor plate through its segmental slots 19, extending through its openings. The floor plate 18 is then turned slightly, wedging it against the floor and then the hopper 15 is secured in position by means of the nuts 28.

It is believed that the many advantages of this invention will be fully understood from the foregoing description.

Having thus described my invention, I

claim:

1. In a floor connection, the combination of a closet bend; a plumblng fixture; a

sleeve extending upwardly from the closet bend and encircling the outlet of the fixture; a floor plate having a series of segmental slots; a flange extending around the outer edge of the plate; inclined flanges on the inner portion of the plate extending around the central opening; inclined toothed racks carried by the inclined flanges having teeth on the bottom and upper faces thereof; a plurality of teeth formed integral with said sleeve whereby the sleeve may be locked against the fixture; and means for holding the plate and the sleeve in thelocked position and the fixture in place above the closet bend, substantially as shown and described.

2. The combination with a closetbend provided with outwardly extending lugs, of a plumbing fixture; and: a reversible floor plate adapted to rest upon the floor and be adjusted about its axis independently of said plumbing fixture, said plate being provided with a plurality of inclined lug engaging fianges, each flange being provided with a plurality of steps on the opposite sides thereof.

3. The combination with a closet bend provided with outwardly extending teeth, of a plumbing fixture; and a reversible floor plate adapted to rest upon the floor and be adjusted about its axis independently of said plumbing fixture, said plate being provided with a plurality of segmental in clined flanges having teeth on opposite sides thereof.

4. The combination with a closet bend extending above the floor and provided with outwardly extending lugs; a plumbing fixture provided with a recessed base to receive the upper end of said closet bend; and a floor plate adapted to rest on the floor and be adjusted about its axis independently of said plumbing fixture and closet bend, said floor plate being provided with an inner cylindrical wall extending beyond the end face of said plate and having inwardly extending flanges formed integral therewith at the outer end of said wall, these flanges having serrations on opposite sides thereof to engage said lugs either when positioned above the floor or below the upper surface thereof.

In testimony whereof I afiix my signature in presence of two witnesses.

THOMAS E. CROSBY.
